AHC: After 1800, what is the maximum number of plausible nations in North America?

Well assuming things from 1800 onwards give a chance for various break away groups to form new states or competing union ideas to take hold:

Maritime Union (NB, NS, PEI, maybe Newfoundland)
"Canada" (from OTL's Quebec to BC)
Republic of New England
United States (sans New England and the South)
Southern Republic (basically the CSA)
Republic of Texas
Republic of Mexico
Mayan State

Theoretically you could fold Texas into the South (or Mexico), the Maya into Mexico, and the Maritimes into Canada and you end up with only 5 states, but 8 seems like the maximum that could plausibly be formed if butterflies go wild post 1800.
 
with 1800 as a pod you can get a fair number

New England or CSA equivalent: Either the US loses New England or it loses the south, but I don't see any circumstances where it loses both.
The various independent states that appear after the CSA collapses but are protected by the French or British to try and keep the US from asserting control over them.
Texas
Republic of Rio Grande
California
New Mexico, though it would probably get divided between Texas and California
filibuster Sonora if Mexico is in really bad shape
Republic of Yucatán/Mayan state if the Yucatan elite gets defeated or maybe even both, with the Peninsula divided.
Deseret
Some kind of Indian confederacy in the northern Great Plains
Quebec
Maritime Confederacy
British Columbia
I want to say 1800 is to late for the Russians, but maybe they pull something out of their asses hold onto their rights to Oregon County and dump the Decembrist and some Poles and other malcontents their later on and they rise up later on.
 
Let's see:
- Canada (as described in the early 1800s, present-day Quebec)
- United States
- Oregon Country (British colony)
- Rupert's Land (indirect British possession through HBC)
- Newfoundland
- Texas
- Mexico
- Several Native American nations as protectorates (I know it was quite possible)
- Central America
Here's the updated version of my post:
(Cross-posting from the Native American nation-states thread)
1. Athabascan Confederacy (Russian-influenced)
2. Rupert's Land (Cree-dominated, but minority languages such as Objiwa, Michif and Bungee Creole are allowed).
3. Iroquois Confederacy.
4. Cascadia (OTL southern British Columbia and most of Washington state (except the areas near Columbia River), Salishan-dominated)
5. Oregon Country (Chinook as the lingua franca)
6. Lakota (OTL North and South Dakota, actually a collection of Siouan peoples)
7. Oklahoma (same as OTL, but Comanche is the lingua franca)
8. Anasazi (most of OTL northern half of New Mexico, dominated by the Kiowas who adapted sedentary lifestyle of their linguistic kin and much of the population have at least a descendant from the native Mexican captives, both male and female)
9. Navajo Nation.
10. Michigan (OTL Lower Peninsula, but dominated by Pottawatomie and other branches of Algonquian peoples)

The rest of North America:
1. Canada (OTL Quebec, Maritime Provinces/Acadia, and a Francophone-dominated Ontario, mostly settled by Huguenots)
2. Newfoundland (Gaelic-speaking nation-state)
3. Nova Scotia (also Gaelic-speaking, OTL Maine)
4. United States of America (much smaller territory than OTL)
5. Texas (trillingual federal republic; it includes OTL Louisiana)
6. Chichimeca (OTL southern parts of California, Arizona, New Mexico and northern Mexican states, formed as a federation of provinces who were formerly separate Spanish colonies)
7. Mexico (in this case, more linguistically diverse than OTL while maintaining Spanish as the language spoken by the majority and official national language)
8. Yucatan (Mayan-dominated nation-state)
9. Central America.
